FIELD OF THE INVENTION

Provided herein is a security mounting bracket device that can be used to connect a cross bar to an object to be mounted for example as a cartop tent, a cargo box or a bike rack.

BACKGROUND

Camping outdoors is a worldwide hobby and a car rooftop tent offers unique advantages that include easy set-up, safer off the ground location and the flexibility to set up camp anywhere a vehicle can reach. Plans on how to make a car rooftop tent can be found on the web and many top brand camping gear manufacturers provide car roof top tent in their product lines. The hardware used to attach the tent to a car roof rack is not included or may focus primarily on ease of attachment. The hardware may be a simple plate, nut, and bolt system or a specialized bracket which is typically easy to remove or leaving a section of a bolt exposed and easily accessible. A bolt cutter can snap the connections in minutes and the tent becomes an easy target for theft. The various mounting hardware also may fail when a car goes off road and the mounted cargo start to angulate.

Thus there is a need for a crossbar mount for vehicle rooftop tents, and other systems to be mounted, that is durable and easy to use, conforms to the shape of various platforms and racks, without compromising the integrity of the mounting bracket device and that protects the mounted system such as a rooftop tent from theft and from vibrating off the mounted structure.

The Security Mounting Bracket Device

Provided herein is a security mounting bracket device that can be used to reversibly secure a crossbar to a mounted object. The mounted object can be for example a rod, a bar, a metal plate or a platform that may or may not include a mounting channel rail. The security mounting bracket device has a custom contoured tunnel formed by the bridge and the mounting posts that can straddle a bar of a selected shape, for example the shape can include a pipe or rod that is round, rectangular, square, elliptical or the bar can be textured with grooves, channels or ridges. The bridge and mounting posts of the device form a tunnel shaped to straddle a cross bar. The tunnel walls are preferably perpendicular to the mounting bracket device bridge forming an angel between the tunnel walls and bridge that is 90°. In further embodiments the tunnel walls are not perpendicular to the bridge forming an angel other than a 90° between the tunnel walls and bridge. As the tunnel portion of the security mounting bracket device is molded out of one piece of material and can vary in length, the angle of the tunnel walls with respect to the line of security mounting bracket device formed between the centers of the two mounting posts can vary for example from 90° to 45° making the angle between the straddled crossbar and the security mounting bracket device customizable. Non-perpendicular crossbar and mounting rail can therefore also be connected by a bolted joint with a security mounting bracket device that is molded with tunnel walls angled to match the angle formed between the crossbar and mounting rail.

The two mounting posts, one on each side of the bridge, include a counterbore hole with a wide well cylindrical hole adjacent to the top of the mounting bracket device and bridge, and a narrower coaxial cylindrical hole at the bottom of the mount. The wider well opening provides a space for a security nut to fit inside the device and to secure a bolt within the bore hole, without leaving the security nut exposed outside of the device. A matching security socket is required to reach the nut and to screw and unscrew a bolt that passes through the bore hole of the device. The narrower cylindrical hole of the counterbore at the bottom of the mounting bracket device serves as the entry point of the bolt that passes through a hole of a primary mounted object, prior to entering the bore hole of the device. The head of the bolt, secured by the device and the security nut, holds the primary mounted object, for example a second bar, a channel guide, a sheet, a plate, or platform, to the crossbar straddled by the bridge and the mounting posts of the device. A secondary mounted object can be attached to the primary mounted object and can include for example a tent, a container, or a bike rack. The secondary object can be fitted with a means of attachment to the primary mounted object, for example a channel guide to secure the object to a bolt connected to a channel slide. In certain embodiments the object to be mounted includes holes for placement of the screws, aligned with the dimensions of the security mounting bracket device, that can form a bolted joint with the security mounting bracket device, straddling a crossbar, and a primary mounted object such as the mounting rail is not necessary.

Optionally the security nut can be replaced with a nylon-insert lock nut or other nut that will form a tight grip with the bolt.

The device is made of a strong hard material that will not be altered by ambient heat and pressure exerted by the cross bar and mounted object and can include material such as aluminum, steel or stainless steel, titanium, zinc alloys or hard plastics. In one embodiment the material is aluminum metal selected for its strength, durability, and light weight. Materials that include metal may be anodized to further reduce corrosion and wear. The choice of the material used are within the level of a skilled artisan.

The device, including exemplary embodiments of the device, will be described with reference to the accompanying drawings.

In a general embodiment, the security mounting bracket device provided herein, includes bridge, mounting posts, a contoured tunnel formed by the bridge and mounting posts, and a counterbore hole within each mounting post.

For example, with reference to FIG. 1 . which illustrate a first exemplary embodiments provided herein, the security mounting bracket device is indicated generally by the reference numeral 10, includes security mounting bracket device mounting posts 12, bridge 13, counterbore hole wells 14. The underside of the security mounting bracket device 10 is exemplified in FIG. 2 includes security mounting bracket device mounting posts 12, bridge 13, and counterbore narrower hole 20 that serves as the bolt entry point. FIG. 3A shows a side cross sectional view of security mounting bracket device 10 with rounded bridge 13, counterbore hole wells 14, and counterbore hole bolt entry ends 20.

The security mounting bracket device 10 bridge 13 and mounting posts 12 form a contoured fit with a crossbar minimizing the space between the mount and crossbar and reducing movement of the mounted object attached to the crossbar, for example reducing vibrationally induced failure of the mount and loss of mounted object when the object is in motion. The minimized space between the mount and crossbar reduces the space that could be accessed for example by a bar to pry the mounted object off the security mounting bracket device. In reference to FIGS. 1-3A, the crossbar with a round shape portion can fit in the contoured tunnel formed by bridge 13 and mounting posts 12. The cross sectional view of security mounting bracket device 10 with rounded bridge, exemplified in FIG. 3A, provides a view of the counterbore wells 14, that reach into the mounting posts 12 and provide an opening for the placement of a security nut. The counter bore spans the entire height of the mounting posts 12 of the mounting bracket device to allow a bolt to pass through the mounting bracket device and form a bolted joint connecting with the mounted object to a crossbar.

The wider cylindrical well of the counterbore provides a space for a security nut to fit inside the device and secure a bolt within the bore hole, without leaving the security nut exposed outside of the device. A matching security socket is required to reach the nut and to screw and unscrew a bolt that passes through the bore hole of the device. The narrower opening at the bottom of the mounting bracket device serves as the entry point of the bolt that passes through a hole of a primary mounted object, prior to entering the bore hole of the device.

The dimensions of the exemplary security mounting bracket device of FIGS. 1-3A are provided in FIGS. 3B-3D wherein FIG. 3B includes height of post 3 h; width of security mounting bracket device 3 w; height of security mounting bracket device to the top of the bridge, 3 r; length of security mounting bracket device 3 s; Width of tunnel 3 t. FIG. 3C provides distance between borehole centers 3 x; diameter of small borehole 3 y; diameter of large borehole 3 z. FIG. 3D provides height of tunnel 3 q; Depth of small borehole 3 u; width of tunnel 3 v. The dimensions provided in FIGS. 3B-3D are of an exemplary device and are in the units of inches. In further embodiments the numerical values of FIGS. 3B-3D dimensions may be representative of the approximate relative dimensions in various units of length.

FIG. 4 illustrates an exemplary security nut that fits within the counterbore cylindrical wells, 14. The security nut has a grooved and/or ridged surface that requires the use of matching security socket to access the security nut.

FIG. 5 illustrates the use of the security mounting bracket device in securing a mounted object to a cross bar. The frontal cross-sectional view of a rounded bridge 13 and security mounting bracket device 10 illustrates the placement of a bolt 51 within the mount, first passed through the first mounted object, exemplary mounting channel slide 52, and through a counterbore hole to a well 14 where the bolt is secured in place by a security nut 40.

An exemplary connection between the primary mounted object and the secondary mounted object is provided in FIG. 6 where the first mounted object, a channel slide 52, is inserted in part within a channel 61 of a mounting rail 60. A mounting rail can be secured to the bottom of a platform for various object including vehicle tent. The mounting of mounting channel 61 to a crossbar 71 by the security mounting bracket device 10 is exemplified in FIG. 7 with a round pipe provided as the crossbar 71. The security mounting bracket device 10, bridge 13 and mounting posts 12 contoured to fit the round shape of a crossbar, straddles the crossbar and its base is tightly secured to the mounting channel slide 52 secured within a mounting rail 60. A bolt 51 end is visible within the well 14 and the security nut is deep within the well (not shown) and preferably not exposed above the well. The security mounting bracket device 10, as shown mounted in FIG. 7 , cannot easily be removed without the use of a security socket that is a complimentary match to the surface of a security nut. The security nut cannot be cut off as it is deep within the security mounting bracket device 10 well 14 and the tight fit between the security mounting bracket device 10 and slide does not provide room for a typical bolt cutter or saw to reach bolt 51. The security nut is preferably positioned below the surface of the security mounting bracket device. Alternatively, a security nut forming a jointed bolt that is positioned partially above the surface of the security mounting bracket device may also be used and preferably requires the use of a matching security socket to remove the nut and the portion exposed above the surface of the security mounting bracket device should not be removable by cutting means.

In further embodiments of the security mounting bracket device, exemplified in FIGS. 8A, 8B and 9 , the shape of a of the security mounting bracket device is customized to fit crossbars of various shapes. The security mounting bracket device 80, as shown in FIG. 8A, is designed to straddle a wide, ridged crossbar as shown in the outline of the bridge 81 and mounting posts 82. The security mounting bracket device 85 and the contour of bridge 86 and mounting posts 87 is designed to straddle a rectangular shaped crossbar (see FIG. 8B). FIG. 9 provides yet another embodiment of a security mounting bracket device 90 with a wide bridge 91 and mounting posts 92 contoured and mounted over a wide crossbar 93 to a rail 60.

In yet another embodiment a security mounting bracket device can connect two or more crossbars to a mounted object. For example, FIG. 10 shows a security mounting bracket device 100 with two bridges and three mounting posts. In this exemplary view the two bridges 101 are designed to secure two round crossbars (not pictured). The two external mounting posts 12 and one internal mounting post 12′ are each fitted with a counterbore well 14 and narrow counterbore end 20 for bolt entry. The central mounting post 12′ may or may not be secured with a bolt and security nut.

Example 2

Placement of a Vehicle Top Tent on a Vehicle Roof Rack Using the Security Mounting Bracket.

An operator places a rooftop tent fitted with two mounting rails on top of two crossbars, crossbar 70 exemplified FIG. 7 , so that the mounting channel 61 is perpendicular to the crossbars 70. Each of four mounting channel slides 52, four mounting channel slides per each mounting rail, hold a bolt 51 that fits into the mounting channel 61 on the two sides of the crossbar 70. The operator places the security mounting bracket device 10 around the crossbar 70 so that the security mounting bracket device 10 straddles the crossbar 70 and the bolts 51 slide inside the counterbore hole bolt entry end 20 through the counterbore hole 14 located in each of the mounting posts 12. Using a proprietary security socket, a security nut 40, is placed onto each of the bolts 51, is fastened forming a bolted joint between the security mounting bracket device and the channel slide of to the mounting rail 60 securing the object, a rooftop tent, to the crossbar 70.

Once all four security mounting brackets, two per crossbar, are fastened tightly across the crossbars 70, the tent will be secured to the vehicle. The tent is safe from theft because the mounts require the use of a proprietary security socket in order to remove the tent and the security mounting bracket device mounting posts 12 are long enough to cover the bolts 51 completely so that bolt cutters cannot be used to cut the bolts and remove the tent. The counterbore hole well 14 is deep so that the security nuts 40 cannot be pried off with pliers. The security mounting bracket device 10 conforms to the shape of the crossbars 70 so that the mounts are more durable and do not bend.

The above example secures a tent with two security mounting bracket device per crossbar. The mounted object may be also secured to a crossbar using one or more security mounting bracket devices per crossbar and the number of security mounting bracket device may be selected by the user and increased in number to accommodate various dimensions of the mounted object.
